LAMP-SHADE.

Application filed October 2, 1916.

To all whom it may concern Be it known that I, xx Hnnsnovrrz, a citizenof the United States, and a resident of Chicago county of Cook, andState of Illinois, have invented certain new and useful Improvements inLamp -Shades, of which the 'lollowing is declared to be a full, clear,and exact description.

This invention relates to lamp shades and its object is to provide alamp shade of simple c(mstruction, capable of being readily and easilyattached to an electric lamp globe or other illuminating device. andheld thereon at. various angles with respect to the longitudinal axis ofthe globe or device. An other object is to provide a holder for theshade, capable ot being readily secured to the shade, and held thereonby reason of its own elasticity, the shade and holder having coactingelements for detachably securing the one upon the other. Another objectis to provide a shade -apable of being secured to the shade holders ofthe connnon and well known electric lighting fixture by means 0t screws,and also capable of being secured to an incandescent electric lamp globeby means of a holder embodying the present; in-

vention. l Vith these and other objects and advantages in view, thisinvention consists in the several novel 'l'eatures of construction,arrangement and combination of parts hereafter fully set forth andclain'led.

The invention is clearly illustrated in the accompanying drawing, inwhich- Figure 1 is a central, vertical section through a lamp shadecontaining the preferred embodiment of the present invention; Fig. 2 isa perspective view of the holder detached from the shade; Fig. 3 is acentral, vertical section of a slightly modified form of the inventionand Fig. l is a central, vertical section of another modified form ofthe invention.

lle'terring first to Figs. 1 and. 2, a lamp shade is illustrated, whichmay be constructed ot metal, glass or other desirable material, and inthe preferred t'orm ot' the invention the shade is formed with anannular groove (3, on its inner face. 'hen the shade is formed of brassor other-sheet metal the groove is made by striking up the metal to forman outwardly projecting annular bead or rib and when formed of glass theshade may be blown or molded withthe bead to provide the annular grooveThe shade. may have a widely flaring shape as Specification of LettersPatent.

shown in Fig. 1 or any desirable shape may be used.

The holder 7, comprises a piece of wire, bent up as best shown in Fig.The middle portion of the wire is bent to form a circular or ring likebase portion 8. of slightly greater diameter than that of tl annulargroove (3. The two end portions of the tvire are bent at t), S), to liein the plane of the circular base portion 8, as at 10, 10, and saidportions; may extend approxinlately parallel with eap'lnother as shown.Beyond said portions lot it), the two ends of the wire are bentaroundlinto two approximately parallel, circular loops ll, 11, whichextend approximately at right angles to the plane of the base portion 8.The two loops 11, 11., are spaced apart a sutlicient distance to permitthem to he swung apart and clipped over the round end of an im-andescentelectric light globe A as shown in Fig. 1.

The holder 7, is secured to the shade 5, by bringing the two arms 10,10toward each other to thereby contract the circular base part 8,whereupon it may be inserted into the annular groove (5 and allowed toexpand thereinto, the elasticity of the wire serving to distend the loopand securely hold it in place in the groove.

The arms 10, 10 serve as tlllClttlllS which the loops 11, 11, may beswung apart to fasten the device upon ail electric light globe, and theloops and arms may swing from the points 9, 5), so that very littleeffort is required to spread the loops apart. in applying the shade toan electric light globe or removing it tl'ieret'rom, although the loopsof the holder act to tirmly hold the shade on a globe while permittingof adjustment of the shade to various positions on the globe. It is tobe noted that when the loops are spread apart and placed on a globe, thecircular base portion is thereby pressed firmly against the bottom ofthe groove, making it upon impossible for the shade to he accidentallydetached from the holder.

In the form illustrated in Fig. 3 the shade member which corresponds toa portion of the shade 5, seen in Fig. 1, has a central opening 12, inits upper side and an annular seat 13, is formed above the bead, 6. Theholder? may be termed in the same manner as the one shown in Figs. 1 and2 if desired. This form of the invention may be used to support a silkshade. paper shade or a shade of other desired material, and lendsitself particularly useful as a shade for candles. i

in the form shown in Fig. 4*. the shade 5" is formed with the annularhead (3' near its smaller end to provide the groove for the reception ofthe holder 7*, and above said bead an outwardly flaring neck portion 1%,by means of which the shade may be secured to the ordinary electriclight fixture (not shown) by the usual. screws employed in the shadeholders of such fixtures and arranged to bear against the outer side ofsaid flaring neck. \Vith this construction the shade may be used inconnection with the holder 7 and may be supported by an electric lampglobe or it may be supported by the Shade holder of the electric lightfixture as desired.

More or less variation of the details of construction are possiblewithout departing from the spirit of this invention; I desire therefore,not to limit: myself to the exact forms of construction shown anddescribed, but intend, in the following claims, to point out all of theinvention disclosed herein.

L I claim as new and desire to secure by Letters Patent:

1. As a new article of manufacture, a lamp shade comprising a shadehaving a top portion having an internal annular groove and a holdertherefor, consisting of a piece of wire bent to form a base portion ofcircular form adapted to be secured in said groove by its ownelasticity, the ends of said wire being bent into two approximatelyparallel bulb clasping' loops extending transversely of the plane of thebase portion and substan-\ tially within the space occupied by' theshade, said loops being; capable of clasping an electric light bulb andholding the shade around the end thereof.

2. As a new article of lamp shade holder comprising: a having aninternal annular groove and a piece of wire bent to foltti a baseportion of circular form adapted to be secured in said groove by its ownelasticity, the ends of said wire beingbent into two approximatelyparallel bulb clasping loops extending transversely of the plane. of thebase portion and substantially within the space occupied by the shade.said loops being capable of clasping an electric light bulb and holdingthe shade around the end thereof.
